My sister has always obsessed about how fat I am. Now I just say: So, I'm fat. You're ugly, I can lose weight...
SHE HATES IT!
One of my girlfriends comes back with "Oh my God, really? I'm FAT??!!!?? Thank you SO much for letting me know, now I'll change my whole life around."
What do people think will happen when they tell you you're fat? Like I care what some stranger thinks.
